REVOLVING-TOP FLAT CAEDI'NG MACHINE.

Application filed August 3, 1925. Serialv 130. 47,959.

This invention relates to revolving top flat carding machines. In theusual construction of a flat carding machine, a sliver of cotton isimpressed forwardly at the feeding end of the machine by a feed roll,from which the cotton is taken by a cylinder designated as a licker-in,revolving in the opposite direction to the feed roll while a cardingcylinder picks up the sliver at the point on the licker-in which issubstantially diametrically opposite the feed roll. The sliver of cottonis carded on the cylinder and carried between revolving flats where itis treated at the end of the flats by a stripper, the sliver then beingremoved by a doffer in the usual manner. The licker-in and feed rollco-operate to remove foreign particles through the co-operation of aroller having comparatively small dimensions.

It is an object of the present invention to provide slots in the housingor cover plate of a fiat carding machine upon opposite sides of thelicker-in, to permit motes and short lint to be removed by knives,adjacent the slots and by means of an air blast which forces the motesand short lint from the sliver through said slots asthe sliver iscarried along by the carding cylinder adjacent the licker-in and atpoints where the lickerin is in close contact with the said feed roll,adiusta-bly mounted rollers being disposed adjacent the slots andsuitably covered for picking upthe short lint and the foreign matterdischarged through the slots.

Another object of the invention is the provision of a slot formed at theV-shaped juncture of the licker-in cover and the back knife plate, theedge of the cover at this pointbeing cut away to provide an elongatedtransverse slot and a pair of knives having a shearing action over thesliver on the carding cylinder andthe film of lint carried by thelicker-inr a draft of air which has'been produced by the revolvingcylinder being driven through the slot to cause. the loose ends of theshort lint to be carried through the slot which have been removed by theknives at the opposite edges of the said slot.

A further object of the invention is the provision of slots, knives androllers for removing short lint and foreign matter from the cardingengine at points along the card ing engine adjacent the feed roll, andalso at points adjacent the dofter, so that a particularly clean sliveris provided at the discharge end of the carding engine which will beequivalent in quality to that produced by the ordinary double cardingprocess.

This invention will be best understood from a consideration of thefollowing detailed description, in view of the accompanying drawingforming a part of the specification: nevertheless it is to be understoodthat the invention is not confined to the disclosure, being susceptibleof such changes and modifications which shall define no materialdeparture from the salient features of the invention as expressed in theappended claims.

In the drawings Figure 1 is a view in perspective of the feeding end ofa flat carding machine, showing my invention applied thereto Figure 2 isa longitudinal vertical section of a flat carding machine showing myinvention in operative position,

Figure 25 is a side view in elevation of a carding machine constructedaccording to the principles of my invention.

Referring to the drawings, in the usual flat carding engine, a cardingcylinder 10 forming the carding device proper has a plurality of teeth11 on its surface which are adapted to be drawn through the sliver forlaying the lint in straight lines and for removing motes. The sliver isfed to the teeth 11 of the cylinder 10 by a licker-in 12, at a pointwhere the licker-in and cylinder are in operative relationship with eachother. The cover 14 for the licker-in and the curved front knife plateare normally in close contact above the licker-in 12 and cylinder 10providing a V-shaped formation as shown at 16. A knife 17 on the loweredge of a stripping plate 15 removes motes and short lint from thesliver which is carried around the cylinder 10. Revolving flats 18 areemployed for the usual purpose. The usual feed roll 19 normally suppliesthe sliver to the licker-in at a point indicated by the numeral 20, thesliver being drawn from a roll of sliver 21.

In the present device an edge of the cover 14 at the V-shaped connection16 is removed to provide a restricted slot 22 and an additional knife 23on this edge of the cover. The co-operating knives 17 and 23 are adaptedto :remove :motes and short lint from the sliver which are forcedthrough the 'restricted slot 22 into engagement with a revo'lv ingroller 25 which has a linen-cover to provide sufiicient frictionalengagement with the lint coming from the slot 22 to collect and roll thelint upon the face oft-he roller.

t will be appreciated that the carding cylinder creates sullicient airdraft to force the lint and motes through the opening 22 during theoperation of the engine.

The roller is provided with projecting spindles 26 and 27 which arereceived within U-shaped bearings 28. Each hearing is formed byproviding" upstandingears at one end of a plate 29. The plates aresecured by means of bolts 30 to the frame of the engine. Each-o1. theplates 29 is provided with a .slot 31 whereby the -.U-shaped journal 28maybe adjusted as desired. The spindle .26 is extended and .isadapted tobe received within a slot 32 formed at one end oi? .a bearing plate 33.A gear 3 l is rigidly connected with the spindle 26 and :meshes with a1ge-ar 35. This gear in turn meshes witha gear 36. The gear 36 is drivenby a .r ear '37 mounted on a shaft 38 which normally forms for drivingelement of the carding engine. The bearing 33 .is provided with aperforation39 adapted to be received by the shaft 38 and intermediateits ends .andnt its lower edge an extension 40 .is provided .hav ing aslot 41 extending from said extension and through a portion .of the bodyof the ,plate 33. A set-screw d2 passes through the slot and issupported by the engine frame so that the plate may be adjusted inpredetermined positions when desired, by oscililating said plate on itspivotal point with the shaft 38. Gears 35 and 36 are carriedrespectivelyyby stub shafts l3 and id mounted on the bearing plate 33.

The cover plate 1% of the l-icker-in is cut away to provide-arestrictedtransverse slot s5 and a :lrnite-edge d6. T hislrnife edge andconsequently the slot adapted to remove what motes and short lint havenot been removed by the knife edges 17 and 23 defining the slot 22. Thelint is collected on a roller 47 located above the slot 45 and isprovided with spindles d8 mounted in Ll-shaped bean .ings .9. Thebearings 49 are substantially :a pair of spaced ears connected to a base.lint passing through the slot4'5 is collected on the surface of theroller 47 which is "I ..-rewise covered wlth linen in order to providethe slot 45 and aid 'thedoor being below a plate 73.

suficient frictional surface to collect the lint. As the diameter of theroll which being constantly covered by the lint, increases, the

lilshafi ed bearin 's e l/ ermit the spindles 48 lint which areordinarily carded to produce a refined sliver. The fact that the roller47 is movable in theslotted bearing d9 permits the roller to drop whenfree of lint adjacent l in preventing the dis charge of lint fromtheslot and thus act as a choke.

At the back end of the engine and below the pn ley 54. which isassociated with an end of the revolving flats 18, I providea pair ofslots and 56st oppositesides of a door A knife edge 58 is provided atthe "lower end of the hack knife plate 59, which is adapted "to furtherremove short lint and motes from the sliver. The slot 56 is provided toDermit lint -r. motes to be discharged which :is collected upon a roller60 which is likewise covered with linen to provide sufficient trictionalsurface for the collection of the lint as it is dischar ed through therestricted slot 'The rollers are provided wit-l a spindle 61 mounted inUshaped brackets '62,

which are similar in construction to the from the sliver.

Gear 34 being in mesh with the 'gear .35 is driven by said gear andsince the diameter of the roller '25 is increased as it takes up andlint, the 'lJ-shaped bearings 28 permit the spindles 26 and 27 to risein the bearings, and also in the slot '32 in the plate 33, whilemaintainingthe gear 34 in mesh with the gear 35. It will be appreciatedthat while ll-shaped bearings permit movement of rollers to accommodatethe increased diameter of said rollers, due to the addition of lint,that it will be necessary to construct .these hearings in such a mannerthat the rollers may be sufi'iciently elevated where it is intended thatthe lint be permitted to accumulate to increase the size of the rollersconsiderably so that the gears on the ends of the shafts .Wlll bemaintained in mesh with the respective driving err.

The rollers 25, l7 andfGO are closely associated with their respectivetransverse slots in order to choke the slots and prevent too great aquantity of air being forced through the same by the air draft producedby the revolving carding cylinder 110. I

Slots other than those shown may be pro- Vided in the licker-in coverand at points along the carding cylinderto permit the escape of lint andmotes.
